Description

Technical Field

[0001] This utility model relates to the technical field of ash conveying pipeline elbows, specifically an ash conveying pipeline elbow for power plants. Background Technology

[0002] Elbows in power plant ash conveying pipelines are used in power plant ash conveying systems. They are mainly used to realize the turning connection of ash conveying pipelines and play a key role in the conveying of fly ash and other materials. They are important components to ensure the stable operation of the power plant ash conveying system, and their performance directly affects the ash conveying efficiency and the system's sealing performance.

[0003] In existing technologies, power plant ash conveying pipe bends typically lack effective thermal expansion and contraction compensation and vibration absorption structures. The thermal expansion and contraction caused by temperature changes during ash conveying cannot be mitigated, and the vibration displacement of the pipe is also difficult to absorb. This can easily lead to stress concentration at the interface between the bend group and adjacent pipes, resulting in leakage problems. In addition, materials can easily get stuck at the corners of the bend group, affecting the smooth flow of ash conveying. In some structures equipped with vibratory motors, the support frame lacks sufficient structural reinforcement design, which can easily deform when the vibratory motor is working, affecting the vibration effect and structural stability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a power plant ash conveying pipe elbow, which solves the technical problems of material stagnation at the corners of the aforementioned bends, affecting the smooth flow of ash conveying, and the lack of sufficient structural reinforcement design in the support frame of some structures equipped with vibrating motors, which easily deforms when the vibrating motor is working, affecting the vibration effect and structural stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power plant ash conveying pipe elbow, comprising: an elbow assembly and a corrugated pipe, wherein the corrugated pipe is disposed at both ends of the elbow assembly, a vibration mechanism is disposed outside the elbow assembly, the vibration mechanism includes a chassis, a connecting frame is disposed at the bottom of the chassis, a reinforcing arm is disposed in the inner cavity of the connecting frame, a pipe clamp is connected to the outside of the connecting frame, the pipe clamp is disposed outside the elbow assembly, a vibration motor is disposed at the upper end of the chassis, a control module is embedded at the upper end of the chassis, the control module is connected to the vibration motor via a line, and a communication device is disposed outside the control module.

[0006] The corrugated pipe can compensate for the thermal expansion and contraction of the pipeline caused by temperature changes during ash conveying, and at the same time absorb the vibration displacement of the pipeline, avoiding leakage due to stress concentration at the interface between the bend group and adjacent pipelines; the vibration mechanism is firmly fitted to the outside of the bend group with pipe clamps, and the reinforcing arm in the inner cavity of the connecting frame can enhance the structural strength of the connecting frame and prevent the connecting frame from deforming when the vibration motor is working; the communication equipment outside the control module can realize remote data interaction with the power plant's central control system, which makes it convenient for staff to monitor the operating status of the vibration motor in real time and adjust the parameters remotely when necessary. The vibration motor can prevent materials from being stuck at the corners of the bend group.

[0007] Preferably, the bend assembly is externally provided with an assembly pipe, which is connected to the bellows via a snap-fit ​​connector, and a sealing gasket is connected between the assembly pipe and the bellows. The assembly pipe, as a transitional connection between the bend assembly and the bellows, simplifies the bellows assembly and disassembly process through the snap-fit ​​connector, facilitating subsequent maintenance and replacement of the bellows. The sealing gasket between the assembly pipe and the bellows fills the tiny gaps at their interface, further improving the interface sealing performance, preventing fly ash leakage during ash conveying, and reducing dust pollution to the environment and energy loss in the ash conveying system.

[0008] Preferably, the corrugated pipe is provided with a flange on its exterior, and bolts are provided on the exterior of the flange. The flange and bolts enable a rigid connection between the ash conveying pipe elbow and other ash conveying pipes in the power plant. The tightening effect of the bolts ensures the stability of the connection and prevents the interface from loosening due to the impact of ash flow in the pipe during ash conveying. At the same time, the flange connection method also facilitates the disassembly and reconnection of the elbow during subsequent maintenance of the ash conveying system, ensuring maintenance efficiency.

[0009] Preferably, a shock-absorbing pad is provided between the vibratory motor and the chassis, and the shock-absorbing pad is made of nitrile rubber. The nitrile rubber shock-absorbing pad has good elasticity and oil resistance, which can effectively absorb the high-frequency vibration generated when the vibratory motor is working, reduce the transmission of vibration to the chassis and the bending pipe assembly, and prevent the bending pipe assembly from developing fatigue cracks or weld cracks due to long-term high-frequency vibration; at the same time, the shock-absorbing pad can also reduce the noise of the vibratory motor during operation and improve the working environment of the power plant.

[0010] Preferably, the inner wall of the pipe clamp is provided with an anti-slip pad, which is made of silicone and has a diamond-shaped anti-slip texture on its surface. The silicone anti-slip pad has good flexibility and friction, and can closely fit the outer wall of the bend assembly to prevent relative sliding between the pipe clamp and the bend assembly; the diamond-shaped anti-slip texture on its surface can further increase the contact area and friction, ensuring that the vibration mechanism maintains a stable position during the operation of the vibration motor, and ensuring the vibration motor's effective cleaning of the bend assembly.

[0011] Preferably, the control module integrates a timing unit and an overload protection unit. The timing unit presets the start and stop times and vibration duration of the vibratory motor. Based on the operating cycle of the power plant's ash conveying system and the ash accumulation pattern of the bend pipe group, the timing unit automatically controls the vibratory motor to start before and after ash conveying, achieving timed ash cleaning without manual operation, thus reducing labor costs. The overload protection unit monitors the operating current and load of the vibratory motor in real time. When the motor current is too high or the load exceeds the limit, it automatically cuts off the motor power supply to prevent the vibratory motor from burning out due to overload and extends the equipment's service life.

[0012] Compared with the prior art, this utility model provides a power plant ash conveying pipeline elbow, which has the following beneficial effects: The ash conveying pipeline elbows in this power plant use corrugated pipes to compensate for the thermal expansion and contraction caused by temperature changes during ash conveying, while also absorbing pipeline vibration displacement to prevent leakage due to stress concentration at the interface between the elbow assembly and adjacent pipelines. The vibration mechanism can be securely fitted onto the outside of the elbow assembly with pipe clamps, and the reinforcing arms inside the connecting frame can enhance the structural strength of the connecting frame, preventing deformation of the connecting frame when the vibrating motor is working. The vibrating motor can also prevent materials from accumulating at the corners of the elbow assembly. The communication equipment outside the control module can realize remote data interaction with the power plant's central control system, facilitating real-time monitoring of the vibrating motor's operating status by the staff.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a technical solution, please refer to Figure 1 , Figure 2 and Figure 3A power plant ash conveying pipe elbow includes: a bend assembly 1 and a corrugated pipe 2. The corrugated pipe 2 is disposed at both ends of the bend assembly 1. A vibration mechanism 3 is disposed outside the bend assembly 1. The vibration mechanism 3 includes a chassis 31.

A control module 32 is embedded at the upper end of the chassis 31. The control module 32 is connected to the vibration motor 33 through a line. A communication device is disposed outside the control module 32.

[0017] The corrugated pipe 2 can compensate for the thermal expansion and contraction of the pipeline caused by temperature changes during ash conveying, and at the same time absorb the vibration displacement of the pipeline, avoiding leakage at the interface between the bend group 1 and the adjacent pipeline due to stress concentration; the vibration mechanism 3 is firmly sleeved on the outside of the bend group 1 by the pipe clamp 35, and the reinforcing arm 36 in the inner cavity of the connecting frame 34 can enhance the structural strength of the connecting frame 34 and prevent the connecting frame 34 from deforming when the vibration motor 33 is working; the communication equipment outside the control module 32 can realize remote data interaction with the power plant central control system, which makes it convenient for staff to monitor the operating status of the vibration motor 33 in real time and adjust the parameters remotely when necessary. The vibration motor 33 can prevent the material from being stuck at the corner of the bend group 1.

[0018] An assembly pipe 22 is provided on the outside of the bend assembly 1. The assembly pipe 22 is connected to the bellows 2 via a snap-fit ​​connector, and a sealing gasket is connected between the assembly pipe 22 and the bellows 2. The assembly pipe 22 serves as a transitional connection between the bend assembly 1 and the bellows 2. The snap-fit ​​connection simplifies the disassembly and assembly process of the bellows 2, facilitating subsequent maintenance and replacement of the bellows 2. The sealing gasket between the assembly pipe 22 and the bellows 2 fills the tiny gaps at their interface, further improving the interface sealing performance, preventing fly ash leakage from the interface during ash conveying, and reducing dust pollution to the environment and energy loss in the ash conveying system.

[0019] The corrugated pipe 2 is externally fitted with a flange 21, and bolts are installed on the external side of the flange 21. The flange 21, together with the bolts, enables a rigid connection between the ash conveying pipe elbow and other ash conveying pipes in the power plant. The tightening of the bolts ensures the stability of the connection and prevents the joint from loosening due to the impact of ash flow inside the pipe during ash conveying. At the same time, the connection method of the flange 21 also facilitates the disassembly and reconnection of the elbow during subsequent maintenance of the ash conveying system, ensuring maintenance efficiency.

[0020] A vibration damping pad is installed between the vibratory motor 33 and the chassis 31. The vibration damping pad is made of nitrile rubber. The nitrile rubber vibration damping pad has good elasticity and oil resistance, which can effectively absorb the high-frequency vibration generated by the vibratory motor 33 during operation, reduce the transmission of vibration to the chassis 31 and the bend assembly 1, and prevent fatigue cracks or weld cracks in the bend assembly 1 due to long-term high-frequency vibration. At the same time, the vibration damping pad can also reduce the noise of the vibratory motor 33 during operation and improve the working environment of the power plant.

[0021] The inner wall of the pipe clamp 35 is equipped with an anti-slip pad. The anti-slip pad is made of silicone and has a diamond-shaped anti-slip texture on its surface. The silicone anti-slip pad has good flexibility and friction, and can closely fit the outer wall of the bend assembly 1 to prevent relative sliding between the pipe clamp 35 and the bend assembly 1. The diamond-shaped anti-slip texture on its surface can further increase the contact area and friction, ensuring that the vibration mechanism 3 maintains a stable position during the operation of the vibration motor 33, and ensuring the vibration cleaning effect of the vibration motor 33 on the bend assembly 1.

[0022] The control module 32 integrates a timing unit and an overload protection unit. The timing unit presets the start and stop times and vibration duration of the vibratory motor 33. Based on the operating cycle of the power plant's ash conveying system and the ash accumulation pattern of the bend group 1, the timing unit automatically controls the vibratory motor 33 to start before and after ash conveying, achieving timed ash cleaning without manual operation, thus reducing labor costs. The overload protection unit can monitor the operating current and load of the vibratory motor 33 in real time. When the motor current is too high or the load exceeds the limit, it can automatically cut off the motor power supply to prevent the vibratory motor 33 from burning out due to overload and extend the service life of the equipment.
